Whittington, Framingharn, Mass., assignor to the United States of America as represented by the Secretary of the Army Filed May 14, 1962, Ser. No. 196,032 8 Claims. (Cl. 52156) (Granted under Title 35, US. Code (1952), sec. 266) The invention described herein, if patented, may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

My invention relates to a ground anchor securing device to hold anchors in loose or sandy soil.

Heretofore it has been extremely difficult to pitch a tent on loose or sandy soil due to the fact that the tent pins or anchors tended to pull out of the ground when the guy lines were pulled taut to support the tent. In addition adverse weather conditions place a strain on the guy lines that frequently dislodge the tent pins or anchors.

It is, therefore, a primary object of my invention to provide a means for securing ground anchors and/or anchor pins in loose or sandy soil.

Another object of my invention is to provide a compact portable device which can easily be carried and operated by one man to secure a plurality of anchors in the ground.

Still another object of my invention is to provide a device for securing varying types of ground anchors and/or ground anchor pins in loose or sandy soil.

An additional object of my invention is to provide a self contained fluid pressure device for securing ground anchors in the ground.

A further object of my invention is to provide a device for securing ground anchors in loose or sandy soil which is simple and economical to manufacture and requires no maintenance.

Other objects and advantages of my invention will be apparent during the course of the following description.

In the accompanying drawing, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same FIGURE 1 is a side elevational view of my device in use with an anchor pin;

FIGURE 2 is a detailed side elevational view of the dispensing unit;

FIGURE 3 is a fragmentary exploded view of the 11pper portion of the anchor pin and the driving cap;

FIGURE 4 is a modification of my invention showing a fragmentary side elevational view thereof; and

FIGURE 5 is a side e'levational view of-the modification shown in FIGURE 4 with the driving rod removed.

In the drawing wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral indicates generally an anchor pin employed in the form of the invention shown in FIGURES 1-3, which comprises an elongated rod 11 having a centrally disposed bore 12 therein, a circular flange 13 adjacent its upper end, and a threaded boss 14 at its upper end. The lower portion of the elongated rod 11 is provided with exterior flutes 15 and a plurality of openings 16 communicating with the bore 12.

A portable dispensing unit generally indicated at 17 includes a container 18 having a threaded neck portion 19 and a concaved base 20. The base 20 has a nipple 21 secured therein providing a passageway 22 having a threaded portion 23. As will be seen in FIG. 2, the nipple 21 terminates above the bottom of the container 18. The container 18 is filled with cement slurry or the like 24 for a purpose to be disclosed hereinafter.

Ice

The container 18 is closed by means of a cap 25 which has a cavity 26 therein. The lower portion of the cap 25 is threaded internally as at 27 so as to engage the neck portion 19 of the container 18.

A nozzle 28 is provided on one side of the cap 25 having a passageway 29 communicating with the cavity 26 and controlled by a manually operative valve 30. On the side opposite the nozzle 28 is a nipple 31 which terminates in an exterior threaded portion 32. The nipple 31 has a passageway 33 extending throughout its length communicating with the cavity 26. A piercing point 34 is secured in the passageway 33 adjacent its outer end by any suitable means. The numeral 35 design-ates a removable hollow handle with an open end 36 having an internally threaded portion 37. A replaceable CO cartridge 38 is carried in the handle 35.

In operation the anchor pin 10 is driven into the ground by any suitable means until the flange 13 is close to the surface. I prefer to utilize a hammer or the like (not shown) and a driving cover 39 (see FIG. 3) which has a cavity 40 adapted to fit over the upper portion of the anchor pin 10 and rest on the flange 13 to protect the threaded boss 14. The nipple 21 of the dispensing unit 17 is then screwed onto the threaded portion 14 of the anchor pin 10. The slurry is poured into the container 18 and the cap 25 is placed on the container 18. The handle 35 is advanced upon the nipple 31 until the piercing point 34 pierces the CO cartridge 38 which enables the gas to escape through the passageway 33 and into the cavity 26 forcing the slurry of cement or the like 24 through the passageway 22 in the nipple 21 and into the bore 12 of the anchor pin 10. The slurry 24 is then forced through the openings 16 and forms a concrete block 41 around the anchor pin 10 and its flutes 15. A tent line or the like (not shown) is then secured to the flange 13 of the anchor pin 10. When this operation is completed and it is desired to release the dispensing unit 17 from the anchor pin 10, the valve 30 is opened to allow the gas in the cavity 26 to escape through the passageway 29 in the nozzle 28. If desired, the container 18 can be filled with slurry 24 prior to attaching it to the anchor pin 10. In this event the nipple 21 can be closed by a cork (not shown) or any suitable means.

The modification illustrated in FIGS. 4 and 5 shows how my dispensing unit 17 may be employed to secure different types of ground anchors. In this form of the invention the anchor 42 includes a stem 43 and carries an anchor line 44 which is secured to the anchor 42 by any suitable means. The anchor 42 is driven into the ground by a driving rod 45 which has a centrally disposed bore 46 having a diameter greater than the diameter of the stem 43 extending throughout its length and is provided with a flange 47 adjacent its upper portion which is threaded as indicated at 48. The driving cover 39 of FIG. 3 is utilized in driving the anchor in the ground. The dispensing unit 17 is secured to the driving rod in the manner said unit is secured to the anchor pin 10 recited in the first mentioned form of my invention. The driving rod 45 is raised slightly prior to piercing the CO cartridge 38 to provide a space indicated at 49 to permit the slurry of cement 24 to escape and form a block of cement such as 50 above and around the anchor 42.

It will be readily appreciated that the blocks of cement (41 of FIG. 1 and 50 of FIGS. 4 and 5) will secure the anchors 10 and 42 in loose or sandy soil where conventional anchors and anchor pins would not hold.

It is to be understood that the forms of the invention herewith shown and described are to be taken as preferred embodiments of same, and that various changes in the shape, size and arrangeemnt of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.
